Cultures in humans and other species are maintained through interactions among
conspecifics. Declines in population density could be exacerbated by culture loss, thereby …

Culture is an outcome of both the acquisition of knowledge about behaviour through social
transmission, and its subsequent production by individuals. Acquisition and production are …

characterize group structure and social associations in a passerine bird.•Juveniles …

Here we examine whether vocal learning in Costa's hummingbird, Calypte costae, is open-
ended. Open-ended learning is the ability of a vocal learning animal to memorize and learn …

Passive acoustic monitoring (PAM) coupled with automated species identification is a
promising tool for species monitoring and conservation worldwide. However, high false …

Variation in bird song occurs at many levels, including between sexes and among
geographic regions. Variation can be due to differences in function, habitat, selection or drift …

Passerines exhibit considerable variations in song characteristics, with crucial ecological,
behavioural and conservation implications. We documented the individual variations and …

Background In short-read DNA sequencing experiments, the read coverage is a key
parameter to successfully assemble the reads and reconstruct the sequence of the input …

Cultural inheritance provides adaptive information at a low cost, and facilitates behavioral
plasticity in response to environmental variation. In non-human animals, cultural traits are …

Songbirds of many species acquire their songs by imitating the songs of conspecific singers.
Conclusive evidence of such imitation comes from controlled laboratory studies, but such …
